Hello from Cali. Been lurking for a while and getting ready to sell my 2006 MCS with 84k. The only significant mods are. JCW pulley and an air intake. It's in great shape but I wanna get this problem solved before any more test drives. I really want to sell it running at 100%. After some research, it seems like a leaning issue and from what gather, I see that there are 380cc injectors that should make nice with the stock computer. I've done all the recommended cleaning, good gas etc. but no change. Wondering if it would be better to try have someone mess with the mapping or just swap out to some 380cc's. If so who makes a plug and play 380 that doesn't need adapters (and not a lot of $).
Any tuners you can recommend in the LA area? I live about an hour north (think Ventura). Thanks

 

Hi bigcontry. Could be a number of things, including a vacuum leak or faulty fuel injection system.

Have you checked the spark plugs? Spark Plug application guide:
